Honeywell thermostat question?

Question

I have one of these pieces of s^^^.   Every time I set it on 66, it goes back to 70.   How can I fix this. 

Answer 1

READ THE MANUAL. I am willing to BET you have a programmable thermostat and you are using the setting to TEMPORARILY override the program until the next scheduled change.

Answer 2

Do a search of the model so that you find the instructions online.  

In general, that POS is for certain programable.  That means it changes based on the program.  So figure out how to set the program.  It will also have a Hold button which should bypass the program.

Answer 3

push hold.
